- WITNESSES HENRY K. KISO, OF NEW YORK, N. Y.

ENVELOP.

Application filed November 14, 1916.

To all whom it may concern.-

Be it known that I, HENRY K. Kiso, a citizen of the Dominion of Canada, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Envelop, of which the following is a full, clear, and exact description.

This invention relates to envelops and has for an object the provision of an improved construction which may be arranged to act as a second class envelop while open or as a first class envelop when closed.

Another object in view is to provide an envelop which in the manufacture produces a minimum waste and yet provides ample overlapping flaps for producing a strong wrapper.

A still further object in view is to provide an envelop and form the flaps in such a manner that a single stamp Will seal a plurality of flaps together.

In the accompanying drawing:

Figure 1 is a plan view of the envelop with one of the flaps folded back so as to better show the construction.

Fig. 2 is a perspective view of an envelop complete, ready for receiving the contents.

Fig. 3 is a perspective view of a completed envelop addressed and ready for receiving the stamp.

Fig. 4 is a view similar to Fig. 1 but with the adhesive differently arranged.

Fig. 5 is a perspective view similar to Fig. 3 with certain parts broken away for better disclosing how the side and end flaps overlap.

Referring to the accompanying drawings by numerals, 1 indicates the body of the envelop and 2 the principal flap arranged at one end, while a flap 3 is arranged at the opposite end and provided with adhesive 4: from one end to near the opposite end. End 5 of flap 3 is not provided with adhesive but may be provided with an ornamenting border 6 if desired. The lower edge of the body 1 is provided with a flap 7 having an adhesive 8 arranged thereon, flap 7 overlapping flap 3 and the end flap 2 overlapping flaps 3 and 7, said end flap being secured to the other flaps by the adhesive 4 and 8.

It will be observed that the end flap 2 is Specification of Letters Patent.

cut away at 9 so that when end flap 2 is properly secured to the flaps 3 and 8 the parts will assume the position shown in Fig. 2 ready for receiving the contents. The cutaway portions 9 leave a section of end 5 eX- posed for receiving a sealing flap 10 havingflap 2 and part of the sealing flap 10, thus sealing all these flaps together.

An ornamental border 13 is provided on the end flap 2 which coacts with the border 6 as well as the border 14: on flap 1O coacts therewith, whereby a distinguishing corner is produced for receiving the stamp and a top panel is produced by the sealing flap 10. This ornamental border in a certain sense hides the edge produced by the flap l0 and also presents a. space in which the return address may be placed, as shown in Fig. '3.

In Fig. 4 a slightly modified form of the envelop is shown in which the flap 7 is not supplied with adhesive whereby the flap 2 is secured only to the flap 3 by the adhesive 4 from the lower edge of the border 6 to line 15 which forms the upper edge of the flap 7. A stamp may be arranged in a similar manner to that shown in Fig. 3 so as to seal flaps 2, 3 and 10 together, but the end flap 2 will not be secured to the side flap 7 whereby the post ofiice inspectors may readily inspect the contents. This allows the use of a one cent stamp instead of a two cent stamp while giving the appearance of a completely sealed envelop. It will also be noted that the flap 7 is held in position by the overlapping of the end flap 2 so that the contents when arranged with their edge behind the said flap 7 will be held against accidental displacement or in a certain sense locked against accidental removal.

What I claim is:

An envelop consisting of a body portion forming the back thereof and having independent fiaps along its lower edge and one end, said body having an extension at its opposite end of substantially the dimensions of, and foldable on, the body, to form the front of the envelop, and externally lapping the said lower and end flaps, and a closing flap along the upper edge of the body externally lapping the upper portion of the said front extension continuously therealong, said closing flap and said extension having portions thereof out away on an angle of approximately 45 to a line drawn centrally through said closing flap and centrally through said front extension to respectively expose portions of the extension and the said end flap Within a reetangular area adjacent one corner of the envelop, for the purpose described.
